Build me a simple React app in this project that feels polished and ready to use.

I want a clean homepage with a nice layout, a header, a main content area, and a footer, plus a few reusable components so the code stays tidy. Make it responsive so it looks good on desktop and mobile, and add a little visual polish with sensible spacing, colors, and hover states. If it makes sense, include a basic example flow with a form or a couple of interactive sections so I can see the app working, not just a static screen.

Keep the setup straightforward and stick with the existing React app structure. Please make sure it runs with the normal start command and builds without errors. If you need to check the latest React guidance or best practices, feel free to look them up online.
